Description

The present invention relates to a vacuum cleaner and, in particular, to a dust collecting device of a vacuum cleaner, which can improve dust collection efficiency. More specifically, the present invention relates to a dust collecting apparatus of a vacuum cleaner, which can increase the filtering efficiency of foreign objects by using a filter assembly installed in a filter chamber in which a swirling air flow is generated, and can make it easy to clean the filter assembly by making it from a plurality of separate elements.
A vacuum cleaner is used to clean a room or other premises by sucking in air containing foreign objects and filtering foreign objects using the vacuum created in it. To filter foreign objects contained in the intake air, a vacuum cleaner with a filter device is provided in the vacuum cleaner.
The filter device is divided into a porous filter made of a porous material and a vortex type filter. A porous filter made of a porous material is designed to filter foreign objects contained in the air when air passes through the filter. The vortex type filter is designed to filter foreign objects using vortex air flow. To reuse a porous filter, the user must clean the filter by removing foreign objects clogged in the filter. It is very inconvenient to clean the filter. In addition, when a large number of foreign objects are clogged, the porous filter cannot be reused. Since the vortex type filter is designed to remove foreign objects from the air using a rotating air stream created by the vortex air stream, clogging of the filter by foreign objects does not occur. For this reason, the vortex type filter has recently been widely used.
Recently, a dust collecting device of a multicyclone type has been created, in which a plurality of cyclone devices are provided for creating a plurality of vortex air flows. Multi-vortex airflows improve the removal of foreign objects. In addition, since there is no need to further install a porous filter in the dust collector, there is no problem of clogging.
However, since the multicyclone type dust collector is designed to remove foreign objects using only swirling air currents, the removal efficiency of foreign objects is still unsatisfactory. Therefore, there is an urgent need to increase the efficiency of removing foreign objects in a dust collecting device of a multicyclone type.
In addition, when foreign objects, such as hair, accumulate in the inner chamber of the multicyclone dust collecting device, the user must remove the foreign objects by hand. This is difficult for the user.
Accordingly, the present invention is directed to a dust collecting apparatus for a vacuum cleaner that substantially eliminates one or more problems due to limitations and disadvantages of the prior art.
An object of the present invention is to provide a dust collecting device and a vacuum cleaner with a dust collecting device, which can increase dust removal efficiency using a swirling air stream.

Therefore, the intake air leaves the main body 100 after filtering foreign objects contained in the intake air.
The suction device is designed to suck in air containing foreign objects when creating a suction force in the main body 100. That is, the suction device comprises a body 1 of a suction brush for suctioning air containing foreign objects using a powerful air stream, a sliding tube 2 exiting the body 1 of the suction brush, extendable and movable by the user, the operating handle 3 provided at the end of the extension tube 2 remote from the center, the control device 4 is provided located on the front of the operating handle 3, a flexible connecting sleeve 5 extending from the working handle 2, a connector 6 connecting the end of the flexible connecting sleeve 5 remote from the center to the main body 100, a tube support 7, by which the extension tube 2 can be supported and suspended, when the vacuum cleaner is not used.
The connector 6 performs the function of a contact transmitting a control signal sent by the user through the control device 4 to the main body 100, as well as an opening through which intake air enters the main body 100. That is, a plurality of electrical contacts are provided at the closest end of the connector 6. However, the electrical contacts only necessary when a control device 4 is provided on the suction device. That is, when the control device 4 is provided on the main body 100, electrical contacts are not provided on the connector 6. In this case, the connector 6 can simply serve as an opening for air passage.
The air entering the main body 100 through the suction device leaves the main body 100 after filtering foreign objects contained in the incoming air. Below will be described in more detail the main body 100 of the vacuum cleaner with reference to figures 1 and 2.
Figure 2 shows the main body of the vacuum cleaner.
As shown in FIGS. 1 and 2, the main body 100 comprises a first base 110 defining a lower portion of the main body 100, a second base 150 located on the first base 110, a cover 200 located on the second base 150, wheels 111 provided on both rear the lateral parts of the cover 200, for ease of movement of the main body 100 and the front support 170 for securing the cover 200 and the first and second bases 110 and 150 with the possibility of support.
The connector 6 is connected to the front support 170 to allow external air to flow into the main body 100. The support 170 is designed to support the cover 200, as well as the first and second bases 110 and 150, thereby reliably supporting the front of the main body 100.
A second base 150 is provided directly above the first base 110 to improve the appearance of the main body and increase the stability of the lower part of the main body.
An exhaust cover 301, configured with a plurality of exhaust openings 302, is provided at the rear of the cover 200 for discharging purified air. The carrying handle 201 is pivotally attached to the upper surface of the lid 200. When the user intends to move the main body 100, he rotates the carrying handle 201 to a vertical position and easily transfers the main body 100, holding the carrying handle 201 by hand.
A dust collecting device 400 is located in the main body on the rear side of the front support 170, and a cyclone element (not shown) is provided in the dust collecting device for creating vortex air flows and filtering foreign objects contained in the air.
As shown in FIG. 3, the dust collector 400 is mounted vertically and is detached from the receiving chamber 151 formed in the main body 100. That is, the dust collecting device 400 can be installed in the receiving chamber 151 by pressing inward and removed from it by pulling it upward.
The front support 170 has a first air inlet 171, and the dust collector 400 has a second air inlet 401 corresponding to the first air inlet 171. In addition, the dust collecting device 400 has an outlet (not shown) located opposite the second air inlet 401. The outlet is aligned with a third air inlet 172 formed in the direction of the electric motor such that the cleaned air, after passing through the dust collecting device 400, exits toward the electric motor side.
In particular, the third air inlet opening 172 has a rectangular shape located along the length in the horizontal direction, thereby contributing to downsizing of the main body 100 and ensuring efficient air passage.
Figure 4 shows the main body of the vacuum cleaner.
As shown in FIG. 4, a second base 150 is located on the rear upper portion of the first base 110. An electric motor housing 300 is located on the rear of the first base 110. In addition, the cover 200 is connected to the first and second bases 110 and 150 to form a main body 100.
In this case, the cover 200 is connected to the first and second bases 110 and 150 in a position in which the front support 170 is connected to the cover 200. The direction of movement of the air entering the motor housing 300 through the third air inlet 172 changes by 90 ° vertically and then changes in the horizontal direction so that air can exit back.
5 shows a dust collecting device according to an embodiment of the present invention.
As shown in FIG. 5, a porous filter such as a sponge is not used in the dust collector 400 in accordance with the present invention. That is, the dust collector 400 in accordance with the present invention is designed to filter foreign objects using swirling air currents. A vortex airflow is generated in at least two chambers that are separated from each other, so that even microscopic dust particles contained in the air can be filtered. This will be described in more detail below.
The dust collecting device 400 comprises a dust collecting device housing 406 having a plurality of filter chambers (see reference numerals 423 and 424 in FIG. 6) for filtering foreign objects and a plurality of storage chambers (see reference numerals 417 and 416 in FIG. 6) for collecting filtered foreign objects, sealing elements 402 and 415 of the chambers, designed to seal the base of the housing 406 of the dust collecting device and to prevent the scattering of foreign objects accumulated in the collecting chambers 416 and 417, the air outlet element 407, laid on the housing 406 of the dust collecting device, for directing the flow of air leaving the housing 406 of the dust collecting device, an element 408 for forming a gap providing a predetermined clearance above the exhaust element 407 for passing air leaving the exhaust element 407 to the side, and a cover device located on element 408 to form a gap.
The cover device includes a first cover 410 that performs the function of the main body of the cover device, a second and third cover 409 and 412, respectively, located at the rear and front of the first cover 410, a cover fastener 411 fastening the first and second covers 410 and 409. The cover fastener 411 to close part of the first cover 410 in order to improve the appearance while fixing the first and second covers 410 and 409.
A cone-shaped filter 405 and a blocking element 404, as well as plates 403 for damping the air flow are located in the housing 406 of the dust collecting device. The cone-shaped filter 405 is designed for efficient filtering of foreign objects during the formation of vortex air flows. The blocking element 404 is located under the cone-shaped filter 405 to prevent the scattering of collected foreign objects. Plates 403 for damping the air flow are made under the blocking element 404 to reduce the speed of the air flow and, thus, for the deposition of foreign objects on the bottom of the storage chambers.
The airflow damping plates 403 and the blocking element 404 can be integral with each other, while the cone-shaped filter 405 can be made as a separate element that can be installed in the blocking element 404. Therefore, when the cone-shaped filter is clogged 405 with foreign objects, foreign objects can be easily removed from the cone-shaped filter 405 by disconnecting the blocking element 404 from the cone-shaped filter 405.
That is, when foreign objects, such as hair or paper, are sucked in and adhere to the outer wall of the cone-shaped filter 405, the suction force is significantly weakened. In this case, the user must remove the foreign objects from the cone filter 405. In this case, the blocking element 404 is first disconnected from the cone filter 405 so that it is convenient for the user to remove foreign objects from the cone filter 405. Since the cone filter 405 has a diameter decreasing downward, the foreign objects , such as hair, can be easily removed by simply pulling it down.
Since the second air outlet 401 is formed corresponding to the upper part of the cone filter 405, a relatively high revolutions per minute is generated in the upper part of the cone filter 405 and a relatively low revolutions per minute is created in the lower part of the cone filter 405 . Therefore, from the bottom of the first filter chamber 423, foreign objects can move into the central part and pass through the openings 426 of the filter 405. To prevent this movement, the filter 405 has a conical shape. In this case, foreign objects do not pass through the openings 426, but are collected in the first filter chamber 423.
In addition, there is a button 413 for opening / closing on the first cover 410 and a lever 414 for opening / closing, the first end of which contacts the button 413 for opening / closing and which rotates when the button 413 is pressed to open / close. The opening / closing lever 414 has a second end in contact with the sealing member 415 of the first chamber. Therefore, when the open / close button 413 is pressed, the open / close lever 414 rotates around a predetermined hinge point. When the second end of the opening / closing lever 414 is removed from the sealing element 415 of the first chamber, the sealing element 415 of the first chamber rotates around a hinge point under the influence of its own gravity and foreign objects collected in the accumulation chambers 416 and 417 as a result of deposition under the action of its own gravity .
In addition, the chamber sealing elements 415 and 402 are designed to properly seal the bottom of the collecting chambers 416 and 417. The first chamber sealing element 415 is pivotally connected to the housing 406 of the dust collecting device so that it can be opened by turning when it is necessary to discard foreign objects stored in the first chamber 416.
A separation plate 437 for separating the first and second filter chambers 423 and 424 from each other and determining the air channel is located on the upper surface of the housing 406 of the dust collecting device.
A plurality of guide ribs 459 are formed on the outer periphery of the dust collector body 406 for guiding the input of the exhaust element 407 around the dust collector body 406. Each of the guide ribs 459 is smoothly rounded at the upper edge for an effective input direction.
Since the outer ends of the guide ribs 459 are designed to contact the inner periphery of the outlet 407, even with an external impact on the outlet 407, the guide ribs can absorb the external impact, thereby preventing damage or breakage of the exhaust 407 from external impact.
The internal structure and operation of the dust collector 400 will be described in more detail with reference to FIG. 6.
As described with reference to FIG. 5, the dust collecting device 400 comprises a dust collecting device body 406, chamber sealing elements 402 and 415 for selectively sealing the bottom of the dust collecting device body 406, a cone-shaped filter 405 installed in the dust collecting device body 406 to increase dust collection efficiency blocking element 404, preventing the scattering of foreign objects collected in the housing 406 of the dust collecting device, plate 403 for damping the air flow to reduce the speed of the air flow and, t Thus, for the deposition of foreign objects on the bottom of the accumulation chambers, an air outlet element 407 located on the housing 406 of the dust collecting device for directing the flow of air exiting the housing 406 of the dust collecting device, an element 408 for forming a gap providing a predetermined clearance above the exhaust element 407 for air passage extending from the outlet member 407 to the side, and covers 409, 410, 411 and 412 located on the member 408 to form a gap.
The dust collecting device body 406 includes an outer wall 418, an intermediate wall 419, and an inner wall 420. The outer wall 418 and the intermediate wall 419 do not extend to the part where the second air inlet 401 is formed, thereby ensuring efficient air passage.
The space formed between the outer wall 418 and the intermediate wall 419 corresponds to the first storage chamber 416, and the space formed between the intermediate wall 419 and the inner wall 420 corresponds to the second storage chamber 417. The inner space formed by the inner wall 420 corresponds to the first filter chamber 423 However, the functions of these spaces vary in accordance with the shape of the dust collector 400.
The operation of said dust collecting device will be described below with reference to air flow.
First, air enters the dust collector 400 through a second air inlet 401. The outer end of the second air inlet 401 communicates with the front support 170, and the inner end of the second air inlet 401 communicates with the first filter chamber 423. The first air supply guide 421 protrudes inwardly from a portion of the inner wall 420 that defines the inner the end of the second air inlet 401 for directing air along the inner periphery of the first filter chamber 423.
When a swirling air stream is generated in the first filter chamber 423, foreign objects contained in the air are deposited and the cleaned air escapes upward through the openings of the cone-shaped filter 405. The second air outlet 401 is formed in accordance with the upper part of the conical filter 405, and in the upper part of the conical filter 405 creates a vortex air flow with a relatively high rpm, and at the bottom of the conical filter 405 creates a vortex air flow with a relative but low rpm. This is the reason for creating a cone-shaped filter 405. That is, since a large number of foreign objects are forced out by an air flow with a relatively high number of revolutions per minute, and a large number of foreign objects are drawn in by an air stream with a relatively low number of revolutions per minute, it is preferable that the filter 405 has the shape of a cone.
The cone-shaped filter 405 may be removably mounted in the center of the separation plate 437 defining the upper wall of the first filter chamber 423. The cone-shaped filter 405 typically has a plurality of openings through which air passes.
The blocking element 404 is located under the cone-shaped filter 405 to prevent the spread of deposited foreign objects. The blocking element 404 has a diameter that increases downward to prevent the scattering of foreign objects. The airflow damping plates are arranged below the blocking element 404 with a predetermined clearance to prevent the impact of the vortex airflow on the deposited foreign objects, thereby mainly preventing the deposited foreign objects from flying apart.
Then, the relationship between the cone-shaped filter 405, the blocking element 404 and the plate 403 for damping the air flow will be described in detail below.
7 shows a cone-shaped filter and a blocking element, which are separated from each other.
As shown in FIG. 7, the cone-shaped filter and the blocking element are separate parts. Plate 403 for damping the air flow is made in one piece under the blocking element 404.
As described above, since the blocking element 404 and the cone-shaped filter 405 are in separate parts, when it is necessary to clean the cone-shaped filter 405, the blocking element 404 is first disconnected from the cone-shaped filter 405. Such foreign objects can then be easily removed from the cone-shaped filter 405, like hair, by simply pulling it down.
In order to easily carry out the operation of connecting and disconnecting, the filter is made in the form of a cone with a diameter decreasing downward.
That is, a cone-shaped filter 405 is provided with a large number of openings 426 through which purified air passes. No openings 426 are provided in the lower part of the cone-shaped filter 405. The lower part, which does not have openings, defines an insertion part 430 (first connecting part), which can be installed in the blocking element 404. At least one first protrusion is provided on the insertion part 430 431 protruding outward. The protrusion 431 performs the function of a fastener for fixing the cone-shaped filter 405 to the blocking element 404 when installing the insert portion 430 in the blocking element 404.
To disconnect the cone filter 405 from the dust collector body 406, the cone filter 405 includes a peripheral abutment surface 432 formed on the upper part of the cone filter 405 and guide ribs 433 protruding on the outer peripheral surface of the upper part of the cone filter 405 and spaced from the abutment surface 432. Support surface 432 is located on the bottom of the separation plate 473.
The blocking element 404 is provided in the upper part with an opening 474 (second connecting part) into which the insertion part 430 can be inserted. An installation groove 427 is provided on the inner periphery defining the opening 474, into which the first protrusion 431 is inserted. A plurality of blanking plates 403 the radial directional air flow is integrally formed on the lower part of the blocking element 404. The upper parts of the air flow damping plates 403 are cut off to define a receiving part 428 in which to install an insert portion 430 inserted into the blocking element 404 is pulled. In addition, on the inner periphery defining the hole 474, second protrusions 429 are provided, directed inwardly on both sides of the mounting groove 427.
Meanwhile, as described above, the cone-shaped filter 405 is made in an appropriate form in accordance with the change in air velocity according to the internal level of the first filter chamber 423, so as to prevent foreign objects from leaving it. With such a cone-shaped filter 405, foreign objects can be perfectly filtered out without the use of an additional porous filter. In addition, foreign objects such as hair accumulated on the outer wall of the cone-shaped filter 405 can be easily removed by simply pulling them down.
In addition, the cone-shaped filter has openings 426 throughout its housing, so that it cannot resist airflow. That is, since the insertion portion 430 having no openings 426 is inserted into the blocking element without opening outwardly, it should be considered that a cone-shaped filter is actually provided with openings 426 throughout its housing. Since the lower end of the cone-shaped filter is substantially narrowed, essentially defining a sharp end, it can actively respond to changes in the speed of rotation of the air flow, thereby increasing the removal efficiency of foreign objects.
In addition, since the blocking element 404 is formed directly below the cone-shaped filter 405, air cannot pass through the blocking element 404, and foreign objects fall along the outer peripheral surface of the blocking element 404. The inner peripheral surface of the blocking element 404 functions in such a way that prevents scattering deposited foreign objects, thus further increasing the efficiency of removing foreign objects.
The operation of connecting the cone filter 405 to the blocking element 404 will be described with reference to FIGS. 7 and 8.
First, the locking member 404 is lifted to a position where the first protrusion 431 is aligned with the installation groove 427. If the first protrusion 431 is not aligned with the installation groove 427, the insert portion 430 cannot be inserted. Thus, the user can easily determine the installation location by rotating the blocking element 404 by a predetermined angle.
Then, when the insert portion 430 is installed in the receiving portion 428, the upper end of the blocking element 404 is in contact with the filter housing 473 of the cone filter 405, and the first protrusion 431 is in contact with the second protrusion 429 with a slight height difference between them. In this position, as shown by the arrow in FIG. 8, the blocking element rotates to the side. Then, the first protrusion 431 passes through the second protrusion 429 to complete engagement. To engage, irrespective of the direction of rotation of the blocking element 404, a second protrusion 429 is formed on both sides of the mounting groove 427. In order for the first protrusion 431 to pass through the inner peripheral surface of the blocking element 404, which is tilted outwardly downward, it is preferable that the upper end of the first protrusion 431 was tilted down at a given angle.
Figure 9 shows the relationship between the cone-shaped filter and the dust collector body.
As shown in FIG. 9, a communicating hole 434 is made in the separation plate 437 through which air coming out of the cone filter 405. A plurality of mounting grooves 435 for the ribs into which the guide ribs 433 are inserted are provided on the inner periphery defining the communicating hole 434. The third protrusion 436 is made on the upper surface of the mounting groove 435 for the ribs in its Central part.
In the description of the fastening operation of the cone filter 405, the guide ribs 433 and the mounting grooves 435 for the ribs are aligned with each other when the conical filter 405 is rotated. Then, the conical filter 405 is lifted so that the guiding ribs 433 pass through the mounting grooves 435 for the ribs. In this position, the gap between the guide ribs and the supporting surface 432 becomes slightly less than the thickness of the separation plate 437.
When the cone-shaped filter 405 is rotated, the separating plate 437 is forced into the gap between the guide ribs 433 and the supporting surface 432, thereby securing the upper end of the cone-shaped filter 405 on the separating plate 437. When the cone-shaped filter 405 is further rotated, the guiding rib 433 contacts the third protrusion 436, such obstructing the turn. When the cone filter 405 can no longer rotate, the user can determine that the assembly is complete and stop rotating.
As described above, the cone-shaped filter 405 may be secured to the separation plate 437 as a separate member. The blocking element 404 can also be mounted on a cone filter as a separate element.
Therefore, when the user is about to clean the cone filter 405, the blocking member 404 is detached from the cone filter 405 in a position in which the cone filter 405 is fixed to the separation plate 437. In this position, the cone filter 405 can be cleaned. When they plan to clean the cone filter 405 using water, the cone filter 405 is cleaned in a position where the separation plate 437 is disconnected from it.
During the fixing process, the cone-shaped filter 405 is secured to the separation plate 437 in a position in which the blocking element 404 is disconnected, and then the blocking element 404 is secured to the cone-shaped filter. If the cone-shaped filter 405 is fixed to the separating plate 437 in a position where the blocking element 404 is fixed thereto, the user will not be able to easily determine the location of the cone-shaped filter 405, since he will not be able to see the combined position of the guide ribs 433 and the mounting grooves 435 for the ribs, since the user's field of view is covered by the blocking element 404. That is, this problem can be solved by fixing the cone-shaped filter 405 on the separation plate in a position in which the blocking element Ent 404 is disconnected from it.
In these embodiments, a design such as protrusions 431, 429 and 436 may be modified. For example, a different engagement design may be used. Alternatively, a mounting groove may be formed on the insertion portion 430, and a protrusion may be formed on the blocking member 404.
In addition, when a plate for damping a relatively large air flow is required, the plate for damping the air flow can be made as a separate part, which can then be fixed to the blocking element.
In addition, as shown in FIG. 6, foreign objects filtered in the first filter chamber 423 accumulate in the first accumulation chamber 416 formed under the first filter chamber 423. The bottom of the first accumulation chamber 416 is sealed by the first sealing element 415. The incoming air passes through the first filter chamber 423, in which foreign objects of relatively large sizes contained therein are filtered out, and then enters the separation plate 437 through a cone-shaped filter 405. Therefore, in order to filter out microscopic foreign objects, an additional vortex air flow is required. This will be described below in more detail.
Air passing through a cone-shaped filter 405 enters the second filter chambers 424 through a second air supply guide 422. Since the second air supply guide 422 is tangential to the inner periphery of the second filter chambers 424, a swirling air flow is generated in the second filter chamber 424.
Foreign objects filtered in the second filter chambers 424 by means of a swirling air stream are deposited in the second storage chamber 417. To prevent the spread of deposited foreign objects, the width of each lower part of the second filter chambers 424 is reduced. In addition, to prevent the spread of deposited foreign objects, the bottom of the second storage chamber 417 is sealed by a sealing element 402 of the second chamber.
The sealing element 402 of the second chamber has a bar-shaped connecting structure that is connected to the sealing element 415 of the first chamber, thereby increasing the internal volume of the first collecting chamber 416. That is, since foreign objects are collected in the space formed between the lower end of the sealing element 402 of the second chamber and the upper end of the sealing element 415 of the first chamber, it is preferable that the connecting structure was made in the form of a bar, which takes up little space.
Air from which foreign objects are filtered in the second filter chamber 424 is supplied to the exhaust element 407 through the air inlet 425 on the exhaust side and is collected in the space between the exhaust element 407 and the gap element 408. Moreover, the diameter of the air inlet opening 425 on the exhaust side is smaller than the inner diameter of the second filter chamber 424 to prevent the passage of foreign objects from the second filter chamber 424 to the exhaust element 407. That is, foreign objects collected on the inner periphery of the second filter chamber 424 do not exit through the air inlet 425 on the exhaust side.
Air from which foreign objects are filtered in the first and second filter chambers 423 and 424 under the influence of swirling air flows enters the electric motor and then exits through the rear surface of the main body 100.
Meanwhile, the lid device is formed on the upper part of the element 408 to form a gap. The cover device comprises a first cover 410, a second and third cover 409 and 412 covering the back and front of the first cover 410, and a lid fastener 411 securing the second cover 409 to the first cover 410.
The operation of said dust collecting device 410 and the overall operation of the main body 100 of the vacuum cleaner will be described below with reference to FIG. 10.
As shown in FIG. 10, outside air enters the main body 100 through the air inlet 171 of the main body 100 and then passes into the dust collecting device 400 through the air inlet of the dust collecting device. Foreign objects contained in the air are filtered out in the dust collecting device 400, as described above, and then the cleaned air passes into the motor housing 300 in a horizontal direction.
The air entering the motor housing 300 in a horizontal direction moves downward and exits through the exhaust holes 302 formed on the rear surface of the main body 100.
In accordance with the distinguishing feature of the present invention, there are many cyclonic devices to ensure complete filtration of even microscopic dust particles without using a porous filter. In particular, a cone-shaped filter is provided in the filter chamber with a relatively large diameter so that relatively large foreign objects can be effectively removed by means of a cone-shaped filter.
In addition, elements such as a filter installed in a dust collector can be easily disassembled and assembled.
The use of the dust collector in accordance with the present invention is not limited to the container-type vacuum cleaner described in the embodiments. That is, the dust collector in accordance with the present invention can be used in other types of vacuum cleaners, such as vertical type vacuum cleaners.
Those skilled in the art will understand that various modifications and changes to the present invention are possible. Thus, it is intended that the present invention include modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
According to the present invention, by using a plurality of cyclone devices, the removal efficiency of foreign objects can be improved.
In addition, by using a cone-shaped filter, which is essentially made in accordance with the vortex air flow regimes, it is possible to increase dust collection efficiency and ease of use. In addition, since there are many openings on the entire cone-shaped filter housing, air flow resistance can be reduced.
Moreover, since the blocking element is formed directly below the cone-shaped filter, foreign objects can quickly settle, and the spread of deposited foreign objects can be prevented.
In addition, since the cone-shaped filter is adapted to be disconnected from the dust collecting device body and the blocking element, it is easy to clean the cone-shaped filter. Moreover, since the blocking element is integral with the plate for damping the air flow, the design can be simplified.
